Hey Joe, do you hear something?

this is the reply I got from my buddy....
This is a cog railway where the power uses cog in the middle of the rail to power itself along the rail. This is only used on very steep grades. It is similar to a rollercoaster climbing that very first hill, although the rollercoaster is much steeper.

The wear on the cog portion indicates that the siding is seldom used. This would be where a cog locomotive could be sent into a roundhouse for repairs, although due to lack of obvious wear on the cogs, I would say it is just a siding, seldom used. When it is used the switch at the far end of the picture would be thrown and the points would direct the loco on to the siding. The straight rail would be moved (it is not obvious how), but the cog rail is then moved over to the usually really hard rubber supports to allow the loco to motivate itself onto the siding. I’ve only seen this on the Mt. xxxxxxxxx just outside Colorado Springs.

That would be the Pikes Peak Cog Railway.

From Manitou Springs to the top of Pikes Peak, one of Colrado's 'Fourteeners' (over 14K feet high).

Pike's Peak Cog Railway - The world's highest cog railroad, the highest Colorado railroad AND highest train in the United States.

Nope, those little warts are IR emittors. The older type head trackers didn't work so well in helicopters due to electronic and electromagnetic interference from overhead controls. This IR based design negates that.

Its the new BAE head tracker as installed on the Eurofighter Typhoon. It was originally designed to be used in our local version of the Apache, the Rooivalk, and as mentioned before was designed specifically with the high interference interior of a helicopter in mind.

At the time also did some very interesting work on eye-trackers (I am not sure if the Typhoon system as implemented includes that particular technology) and through-armour vision.

I get it now, the two drive rails are tied together, so the mains never have to pass over/under the cogs. http://forums.pelicanparts.com/uploa...1294923703.jpg
Here's what you get when you have a high end computer company send movers so as to not void your warranty.

I see my award finally came in.
